直に取り付けられている。 FIG. 3 shows this type of reserve tank, in which a cap 7 is removably attached to the upper opening 3 of the tank body 1 via an annular gasket 5. Then, the cap 7
An inlet/outlet pipe 9 that connects to the radiator cap via a tube and a drain pipe 11 that discharges the pressure inside the tank body 1 to the atmosphere are inserted into the inlet/outlet pipe 9.
A guide pipe 13 is installed vertically toward the tank bottom 1'.

水が満水となるように調整している。 The reserve tank having such a configuration stores the cooling water W released from the radiator cap into the tank body 1 through the inlet/outlet pipe 9 when the cooling water inside the radiator reaches a predetermined pressure due to temperature expansion or the like. Also, when the cooling water inside the radiator becomes negative pressure due to contraction etc., the cooling water W inside the tank body 1 is stored through the inlet/output pipe 9.
is introduced into the radiator to adjust the amount of cooling water in the radiator to be full.

In this way, the reserve tank temporarily stores the cooling water W in response to fluctuations in pressure within the radiator.
In addition, it has a function to return this cooling water W into the radiator as appropriate, but the cooling water W discharged from the radiator (radiator cap) contains a lot of garbage G, and conventionally, this garbage G is Precipitation was found throughout the bottom 1' of the reserve tank. When the radiator became under negative pressure, this garbage G was sucked into the guide pipe 13 together with the cooling water W and introduced into the radiator, so the garbage G adhered to the seal part of the negative pressure valve of the radiator cap. As a result, there was a risk that the function of the negative pressure valve would be impaired due to long-term use.

The present invention was devised in view of these circumstances, and provides a reserve tank that reduces the amount of dust in the cooling water introduced from the reserve tank to the radiator and prevents deterioration of the function of the negative pressure valve of the radiator cap. The purpose is to

In order to achieve such an object, the present invention provides a reserve tank in which a cap is detachably placed in the upper opening of the tank body, the cap is inserted through the cap, and the tip of the pipe is placed near the bottom of the tank body. In this, an annular protrusion is provided at the bottom of the tank body, the central axis of which is approximately the same as that of the pipe, and the inner diameter of which is larger than the outer diameter of the pipe.

According to the present invention, the cooling water flowing into the reserve tank from the radiator collides with the inner bottom of the annular projection and then sequentially flows to the outside of the annular projection, but the dust in the cooling water is removed by the force of the water flow into the annular projection. As a result, it is washed to the outside of the annular protrusion and precipitates. Then, when the inside of the radiator becomes negative pressure and the cooling water returns to the radiator, the dust that has settled on the outside of the annular projection is blocked by the annular projection, thereby reducing the amount of dust that is sucked into the pipe. It happens.
以下、本考案の実施例を図面に基づき詳細に説

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Incidentally, the same elements as those in the conventional example described above are given the same reference numerals, and the structural description thereof will be omitted.

5, an annular protrusion 17 having an inner diameter p larger than the outer diameter o of the guide pipe 13 and a height h higher than the lowest part 13' of the guide pipe 13 is provided on the bottom 15' of the tank 15'. It is characterized by being integrally provided coaxially with the pipe 13. Furthermore, a drain stock 19 is provided on the tank bottom 15' outside the annular protrusion 17, and by operating the drain stock 19, the cooling inside the reserve tank can be maintained without having to remove the cap 7 one by one when replacing the cooling water W. Water W can be drained.

３から吸引されることがない。 In this embodiment configured as described above, the cooling water W flowing into the reserve tank from the radiator
After colliding with the inner bottom of the annular projection 17, the debris G in the cooling water W does not settle within the annular projection 17 due to the force of the water flow into the annular projection 17, but instead flows out of the annular projection 17. It will flow outside the protrusion 17 and settle on the tank bottom 15'. As a result, the inside of the radiator becomes negative pressure, and the guide pipe 1
When the cooling water W is introduced into the radiator from 3,
Most of the debris G settling on the outside of the annular projection 17 is blocked by the annular projection 17 and the guide pipe 1
There is no suction from 3.

負圧弁の機能が良好に維持されることとなつた。 As described above, according to this embodiment, when the cooling water W is introduced into the radiator through the guide pipe 13 and the inlet/outlet pipe 9, most of the dust G that has settled in the reserve tank is removed from the annular protrusion 17. Since it is not blocked by the guide pipe 13 and is not sucked from the guide pipe 13,
The amount of dust G introduced into the radiator is reduced, and the adhesion of dust G to the negative pressure valve of the radiator cap is reduced, so that the function of the negative pressure valve is maintained well even after long-term use. The day came.

副次的な効果も有する。 Further, in this embodiment, since the drain tank 19 is attached to the tank bottom 15', there is no need for the troublesome work of removing the cap 7 one by one and draining the cooling water W when replacing the cooling water W.
Furthermore, since the annular protrusion 17 is provided on the tank bottom 15', there is a secondary effect of increasing the strength of the tank body 15.

を妨げる得る高さを有することが必要である。 It is preferable that the annular projection 17 is formed integrally with the tank body 15 during blow molding.
After blow molding the tank body 15, the upper opening 3
You can also insert it and paste it. In addition, in the above embodiment, the height of the annular projection 17 is set to the height of the guide pipe 1.
Although it is formed higher than the lowest part of No. 3, it may be formed lower than the lowest part. However, even in this case, the annular projection needs to have a height that can prevent the dust G from being sucked into the guide pipe 13.
また、本考案は、出入パイプ９やドレンパイプ
１１がキヤツプ７に一体に設けられたリザーブタ
ンクにも適用できることは勿論である。 Furthermore, it goes without saying that the present invention can also be applied to a reserve tank in which the inlet/outlet pipe 9 and the drain pipe 11 are integrally provided with the cap 7.

As described above, according to the present invention, the amount of dust introduced into the radiator together with cooling water when the pressure inside the radiator is negative is reduced, so even after long-term use, the negative pressure valve of the radiator cap The functions of the system were maintained well.
